Re: Another EV bike :)

Hi Chris, Looks like you will have some smart packs there. Be very interested to see what sort of performance you get from them.

Re: British gas charging station yes or no

Also, it is a station with a J1772 connector - is the charger in your car a smart type of charger that will accept this connection?

Re: Another EV bike :)

well, I for one am looking forward to seeing this pack being built. and it will be interesting to see how it performs.

Another question I was just thinking of - do you have any idea on the size ( volume ) the pack will be, and an estimated weight at all?

Re: Another EV bike :)

Well, I for one will be interested to see how you progress with your pack. How will you assemble it? Will you be using the cell holders and have them all wired up that way? I used to work for major electronics company in IT - and we used to have piles of defunt laptop battery packs. I used to disman...

Re: Another EV bike :)

Hi Chris - my mistake, I did not take in to account the voltage of the lipo in my calculations. A single cell is what 3.2v nominal voltage, by 1400 mah = 4.48 watt hours ( call it 4.5 ) and you have 700 which make a total of 3.1 kwh. I stand corrected. Will be interesting to see what performance you...

Re: Another EV bike :)

Hi Chris - have you worked out your total pack size at all. I have done some quick maths from your posts and it seems that you have got a fairly small overall pack size. You lead acid pack would be 900 watt hours and your lipo pack roughly 1200 watt hours - so about a 2.1kwh pack. Now if you say you...

Re: Another EV bike :)

Wow Chris, that looks like lots of work being done there. I am thinking of putting together a few smaller cells to make a 12 volt battery to run my camping fridge. Want to make a simple BMS to cut it off from over charge and discharge, and I would like to assist the battery with my small mobile sola...
